CALENDAR-CLOCK.

SPECIFICATION formingpart of Letters Patent No. 249,536, dated November15, 1881.

Application filed April 15, 1881.

To all whom it may concern:

Be it known that I, BENJAMIN B. LEWIS, of Bristol, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Calendar-Clocks; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains make and useit, reference beinghad totheaccompanyingdrawings,which form part of thisspecification.

My invention relates to an improvement in calendar-clocks, the objectthereof being to indicate on a combined three-faced dial and by threedistinct indicators the month, day of the month, and day of the week.

With this object in view, my invention consists, first, in combiningwith calendar mechanism adapted to indicate the month of the year, andthe day of the month, and patented to me by United StatesPatents Nos.34,341 and 85,456, a wheel-train arranged to connect with and beactuated by the month-wheel of the calendar mechanism aforesaid toindicate the month on one face of the three-faced dial.

My invention further consists in combining with the calendar mechanismpatented to me, as aforesaid, devices to he diurnally operated therewithand adapted by pawl-and-pinion mechanism to indicate on one face of thethreefaeed dial the day of the week.

My invention further consists in certain details of construction andcombinations of parts to be hereinafter described, and pointed out inthe claims.

In the accompanying drawings, Figure l is a view of a combinedthree-faced dial provided with indicators to indicate respectively themonth, day of the month, and day of the week. Fig. 2 is a plan View ofmy patented calendar mechanism provided with my newly-invented devicesfor actuating the month and day-ofthe-week indicators. Fig. 3 is a Viewthereof with the click-lever pawl, numeration, and February wheelremoved; and Fig. 4 is an underside view of the numeration and notationwheel.

(ModeL) scribed in these patents will not be herein described furtherthan necessary to a complete understanding of my present invention.

The calendar mechanism is operated by suit- 5 able devieesconneci ingwith the clock adapted to diurnally operate itscliclr-lever 7) andspringpressed pawl 13 to more the numeratiou and notation wheel D,containing thirty-one teeth,

together with the February or compensation wheel E, one notch for everyday, except as other devices may operate to impart to them a more rapidmotion.

In the drawings, the right arm of the clicklever is bent outwardly andadapted to be attaohed to a diurnally-reciprocating rod actuated by theclock mechanism.

The indicator B on the week-day dial is operated by avertically-reciprocating bar, B

sliding in guides L L and provided with an meshcs'with a seven-pillarcdpinion, b, upon the shaft B of which the indicator B is mounted. Aspring, C, engages with the teeth of wheel [and prevents it from beingcarried too lar forward and, by revolving the pinion,

from causing an incorrect day to be indicated.

The indicator Q, which indicates the month and makes an annualrevolution, is operated by a train connecting with the compensationwheelB and notched numeration and notation wheel A, said wheels being mountedon a hollow socket, I, through which passes the shaft J, to which thewheels D and E are secured. The first wheel, M, of the train referred tois attached to the socket I and partakes of every movement thereof. Thesaid wheels B 0 and A are operated in monthly motion by devicesconnecting-them with the diurnally-moving wheels D and E, and are alsoadapted to periodically perform peculiar functions that they maycorrectly calendar and keep pace 5 with the changing months, and executethe necessary leap-year changes. These wheels and auxiliary devices formno part of this invention, and as they are fully described in Patents N0. 34,341 and No. 85,456, detailed description of them is unnecessary.

The wheel M before alluded to is shown in three distinct faces, thefaces S and T respectively indicating the month of the year and the daysof the week, being located within and eccentric to that face U of thedial which is encircled by a series of figures representing the days ofthe month, which are indicated by pointer V, provided with sleeve Y,adapted to receive the shaft J actuated in daily motion by thenotation-wheel D.

.The calendar mechanism is itself attached to a plate, a, secured to asecond plate, 0, riveted to the back of the dial R, the said plate 0being slightly elevated above the back of the dial to avoid interferencewith the eccentric dial-faces S T, the dial-rims of which are insertedthrough the large dial and secured at their rear edges to the plate 0,whereby said dials are sunken with relation to the dialfaee U.

The advantages gained by securing themechanism directly to the back ofthe dial is that the different pointers V313 and Q may be permanentlysecured in their proper positions, thus avoiding the danger and troubleofbeing misplaced and incorrectly adjusted by those not'familiar withcalendar mechanism.

It has been an objection to the dial-calendars heretofore constructedthat the complication and figuring of the dials have been veryconfusing. My invention is intended to obviate such ditticulty by acombined three-faced dial, each dial being devoted to the indication ofa single change.

The calendar mechanism, together with its auxiliary attachments, issimple in construction, requiring but little power in its operation, andwhen properly set and adjusted will fulfill with accuracy and precisionits designated functions.

I would have it nnderstool that I do not limit myself to the exactconstruction shown and described, but hold myself at liberty to makesuch slight (changes and alterations as fairly fall within the spirit ofmy invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is v 1. The combination, with a three-faceddial and calendar mechanism mounted on the shaft, of theday-of-the-month hand or indicator, said calendarmechanism beingconstructed and arranged substantially as shown and described, andadapted to actuate the day-of-the-month hand to properly indicate thedays of the different months of the year, of a day-of-the-week hand orindicator, and month-of-the-year hand or indicator, attached toindependent shafts, and intermediate mechanism for actuating said hands,substantially as set forth.

2. The combination, with calendar mechanism, snbstantially as shown anddescribed, for calendaring the month and days of the month, of apinion-shaft provided with a hand that indicates the days of the week ona separate dial, a toothed wheel meshing with said pinionshat't, and aslide-bar provided with a springpawl which engages with said toothedwheel, said slide-bar being arranged to be actuated simultaneously withthe click-bar of the calendar, substantially as set forth.

3. The combination, with calendaring mechanism, substantially as shownand described, for calendaring the month and days of the month, of awheel-train connected with and actuated by the month-wheel of saidcalendar mechanism, and arrangedto revolve the month of-the-year hand orpointer, and a pinion-shaft provided with a hand that indicates the daysof the week on a separate dial, a toothed wheel meshing with saidpinion-shaft, and a slide-bar provided with a spring-pawl which engageswith said toothed wheel, said slide-bar being arranged to besimultaneously actuated with the click-bar of the calendar,substantially as set forth.

4. The combination, with a day-of-the-month dial and sunk dials forindicating the days of the week and months of the year, said sunk dialsbeing attached to a plate, a, secured to the rear face of theday-of-thc-month dial, of calendar mechanism mounted on a plate, a,which is attached to plate 0, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this5th day of April, 1881.
